What are the types of permanent magnets? There are three main performance parameters to determine the performance of the magnet:
Remanence Br: When the permanent magnet is magnetized to the technical saturation and the external magnetic field is removed, the retained Br is called the residual magnetic induction.
Coercive force Hc: The B of the permanent magnet magnetized to the technical saturation is reduced to zero, and the added reverse magnetic field strength is called the magnetic coercive force.
It is called coercivity.
The magnetic energy product BH: represents the magnetic energy density established by the magnet in the air gap space (the two magnetic pole spaces of the magnet), that is, the magnetostatic energy per unit volume of the air gap. Since this energy is equal to the product of the Bm and Hm of the magnet, it is called the magnetic energy product.
Magnetic field: The space that magnetically acts on the magnetic pole is a magnetic field.
Surface magnetic field: The magnetic induction at a specified position on the surface of a permanent magnet.
How to choose a magnet?
Before deciding which magnet to choose, what role does the magnet need to play?
Main role: moving objects, fixing objects or lifting objects.
The shape of the required magnet: a disk shape, a circular shape, a square shape, a tile shape or a special shape.
The size of the required magnet: length, width, height, diameter and tolerance, etc.
The suction of the required magnet, the expected price and quantity, and so on.
The compass is invented according to the nature of the magnet.
